QEMU (aka Quick Emulator) built to use ‘address_space_translate’ to map an
address to a MemoryRegionSection is vulnerable to an OOB r/w access issue.
It could occur while doing pci_dma_read/write calls. Affects QEMU versions
>= 1.6.0 and <= 2.3.1. A privileged user inside guest could use this flaw
to crash the guest instance resulting in DoS.
